Abstract

A control system including an input component configured to receive an input and generate control information in response to the input; a communication link coupled to the input component; and a plurality of control components, each of the control components coupled to the input component through the communication link and configured to receive the control information and to actuate an associated actuator in response to the control information.

Claims

1. A lighting control system, comprising:

a plurality of lighting system input components;

a plurality of lighting system control components, wherein the input components do not contain any information about the control components other than an associated address for each control component, and the control components do not contain any information about the input components other than an associated address for each input component;

a communications link communicatively coupling the plurality of lighting system input components and the plurality of lighting system control components so that each of the plurality of lighting system input components can communicate directly with each of the plurality of lighting system control components through the communication link so that a central controller is not needed to process the information from the plurality of lighting system input components; and

a master component communicatively coupled to the communications link, the master component configured to maintain a schedule of operating mode changes and to transmit a schedule change signal to change the operating modes through the communications link in accordance with the schedule, wherein an operating mode is a configuration that determines how a control component operates.

2. The lighting control system of claim 1, wherein the schedule comprises time related schedule information.

3. The lighting control system of claim 1, wherein the schedule comprises event related schedule information.

4. The lighting control system of claim 1, wherein the schedule defines weekdays and weekends.

5. The lighting control system of claim 1, wherein the master component is configured to transmit the schedule change signal in response to an input.

6. The lighting control system of claim 1, wherein the input comprises one of a user input or a command from an external source.

7. The lighting control system of claim 1, wherein the schedule change signal contains instructions to change between operating modes with no reference to any underlying stimulus.

8. The lighting control system of claim 1, wherein the master component transmits the schedule change signal through the communications link to at least one of the input components.

9. The lighting control system of claim 1, wherein the master component transmits the schedule change signal through the communications link to at least one of the control components.

10. The lighting control system of claim 1, wherein the master component transmits the schedule change signal through the communications link to each of the input components and the control components.

11. The lighting control system of claim 1, wherein at least one of the input components responds to the schedule change signal.

12. The lighting control system of claim 1, wherein at least one of the control components responds to the schedule change signal.

13. A method of operating a lighting control system, comprising:

establishing the lighting control system with a plurality of input components, a plurality of control components, and a communications link communicatively coupling the plurality of input components and the plurality of control components so that each of the plurality of input components can communicate directly with each of the plurality of control components through the communication link so that a central controller is not needed to process the information from the input components;

wherein the input components do not contain any information about the control components other than an associated address for each control component and the control components do not contain any information about the input components other than an associated address for each input component; and

maintaining, at a master component, a schedule of operating mode changes, wherein an operating mode is a configuration that determines how a control component operates; and

transmitting, from the master component, a schedule change signal through the communications link to change the operating modes.

14. The method of claim 13, wherein the schedule comprises at least one of the group consisting of:

time related schedule information;

event related schedule information; and

schedule information defining weekdays and weekends.

15. The method of claim 13, wherein the master component transmits the schedule change signal in response to an input.

16. The method of claim 13, wherein the schedule change signal contains instructions to change between operating modes with no reference to any underlying stimulus.

17. The method of claim 13, wherein the master component transmits the schedule change signal through the communications link to at least one of the input components.

18. The method of claim 13, wherein the master component transmits the schedule change signal through the communications link to at least one of the control components.

19. The method of claim 13, wherein the master component transmits the schedule change signal through the communications link to each of the input components and the control components.
